CUBT BALTI-IASAR, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO JOHN WV. FRYER, OF SAME PLACE.

VALVE FOR STEAM -RADIATORS.

SPECIFICATION forming part of Letters Patent No. 619,264, dated February 14, 1899.

Application filed March 1, 1898. Serial No. 672,132. (No model.)

To all whom, it may concern:

Be it known that I, CURT J. BALTHASAR, of New York city, county and State of New York, have invented an Improved Valve for Steam- Radiators, of which the following is a specification.

This invention relates to an improved valve for steam-radiators which permits the radiator to be readily coupled to the steam-pipes and in which both the inlet and exit ports are simultaneously opened and closed by a double arrangement of valve disks on a common valve-stem, thus greatly simplifying the operation of turning the steam on or off.

In the accompanying drawings, Figure 1 is a vertical section, partly in elevation, of my improved valve on line 1 1, Fig. 2, and showing it coupled to a radiator. Fig. 2 is a section, partly in elevation, of the valveon line 2 2, Fig. 1, and showing the valve-disks in a different position; and Fig. 3 is a bottom view of the valve.

The letter a represents the valve-casing, divided by two transverse perforated partitions a a constitutinginlet and intermediate ports, into three chambers a a a. The valvestem bis threaded at 1) into the valve-cap and carries two valve-disks 19 12 Of these the lowermost disk b is fitted upon the stem within chamber a and is adapted to be seated when lowered upon the perforated bottom a of the valve-casing, which constitutes the exitport, while when the disk 6 is raised it will close the opening in partition a Fig. 1. Fingers b projecting upwardly from valve-disk b and into the openings of partitions a a, properly guide the valve in its motion.

The upper valve-disk b sits yieldingly upon its stem within chamber a and is held against an abutment or sleeve 0 by a spring 0. W hen lowered, this upper valve-disk 19 seats upon port a, while when raised it is received within the upper part of chamber (L The uppermost chamber a connects directly with a leg a which is adapted to be coupled to the steam-supply pipe, while the lowermost chamber a connects by port a with an elbow ad, which is adapted to be coupled to the return-pipe. The upper or transverse arm of this elbow is arranged beneath chamber a and at right angles to leg a The chambers a a communicate with a laterally-extending arm a of casing a, which is adapted to be coupled to a steam-radiator A by coupling (Z. The arm a is divided into an upper inlet-passage a and a lower returnpassage a by a lateral extension of partition a that forms a diaphragm within such arm. This diaphragm connects with a corresponding diaphragm d of coupling d, which is thus also divided into an upper inlet-passage d and a lower return-passage d.

To turn on the steam, Fig. 1, the valve is raised so that the disk b will open inleirport a, while disk I) will open exit-port a and close intermediate port a so as to out 01f direct communication between chambers a a. The circulation will be as follows: from leg a to chamber aflthrough inlet-port a to chamber (1 thence through passages a d to radiator A, and back through passages d a, chamber a, exit-port a and elbow a To shut off the steam, Fig. 2, the valve is lowered, when the port a will be closed by disk I) and the port a will be simultaneously closed by disk b while the intermediate port a will be open.

It will be seen that by my invention both the steam inlet and exit ports are controlled by the motion of a single valve-stem and that the valve-casing is coupled to the radiator by means of a single coupling, thus avoiding a multiplicity of connecting-pipes.

What I claim is- A valve for steam-radiators composed of a casing having an inlet-port, an exit-port, an intermediate perforated partition, a waterinlet leg communicating with the inlet-port, an exhaust-elbow communicating with the exit-port,and having an upper transverse arm arranged at right angles to the inlet-leg, and a valve-stem having a pair of valve-disks adapted to engage the ports, substantially as specified.
